Highlight data path after Simulation

Hello,

I have a model which looks like this :

In Equipement2 block for example :

In ETAFON1 block for example :

In this example i have only put 2 variable "true" (to make equipement2 red) and i would like to know if it's possible to follow/highlight the path of the signals which started from "true" variable or to know why an equipement is red by following the signal in reverse direction ?

Thanks you !
